Abstract
A flow regulator for catheters and similar devices and a process for their manufacture. The regulator consists of a tube having both cross-sectional and longitudinal dimensions of pre-determined precision, the regulator having extended tubular extremities for connecting to the catheter feed system. The manufacturing process includes the insertion of an axially mobile internal rod concentric with the tube, followed by molding stage by flattening the tube around the internal rod which is inside the tube, high frequency heating of the tube around the internal rod to heat internal regions of the tube, and then, after suitable cooling period has elapsed, withdrawing the internal rod to leave the tube with its precisely dimensioned bore.
